Assessment

Why?

Strongest counted support: The abstract reports the screening scale, three fossils, their layer age range, and proteomic Denisovan identification. weight 2.000000 evidence

Suppressed as dependent: The excerpt directly states that more than 60,000 fragments were screened and three hominin fossils were identified and confirmed Denisovan.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Supported.

  The abstract directly reports the fragment count and three identified Denisovan fossils.

• The excerpt directly states that more than 60,000 fragments were screened and three hominin fossils were identified and confirmed Denisovan.

  The passage explicitly supports the claim’s count, location, and Denisovan identification.

• The primary Nature study reports screening more than 60,000 fragments and identifying three hominin fossils.

  Primary archaeological and proteomic report.

Evidence against

None.

Qualifications

• The source specifies that 76 fragments underwent ZooMS selection and 17 underwent proteomic sequencing after screening more than 60,000 fragments.

  From Ancient proteins identify various Denisovan remains from Southwest China Read 2026-09-29 Relevance DIRECT Steps 0 Counted

  The staged sampling materially bounds interpretation of the three identified fossils; it does not negate the reported result.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
